GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 235,537, dated December14, 1880.

Application filed August 20, 1879.

To albwlwm it may concern Be it known that I, JACOB D. JoNEs, ofWinchester, in the county of Frederick and State of Virginia, haveinvented certain new and useful Improvements in Grain-Binders, of whichinvention I hereby present a full specification,-reference being had tothe accompanyinglettered drawings, forming a part hereof.

My invention relates to that class of grain- IO binders which'isattached to and actuated by harvesters or reapers, automatically tyingthe grain as it is delivered in proper shape and 'quantity, and hasspecial reference to the devices for making the loop and knotting it. Ido not claim any special device for deliveringthegrain to the binder,nor any special device for throwing the cord around the grain, though Iattach a spring to the throwing-arm so connected with the spoolsupplying the tying-cord as to take up the slack or yield to the strain,(a variety of such spring is shown in Fig. 8,) having found byexperience that throwing-arms so provided are the best.

For'distinctness in the drawings, the throwin g-arm and the devices fordelivering the grain to the binder are omitted.

In the accompanying drawings, Figure l is a side elevation of mymachine. Fig. 2 is a top 'view. Fig. 3 is a sectional detail of the-tube T,"&c. Figs. 4 and 5 are views showing 'details of the tyingprocesses. Fig. 6 is afront view-of the jaws, &c. Fig. 7 is a detailview of the latchL and cord-carrier K. Fig. 8 shows a methodof attachinga take-up spring to a 5 throwing-arm. Fig.9 is a detail view showingthearrangement of the latch or spring L in -thetube T.

In these drawings, A, A, A A and A are standards or parts of the frameof my machine, aifording supports and bearings. B is thedriving-shaft orrod, connected with and actuated by the harvester or reaper. Upon thisshaft B is a segmental bevel-gear wheel, f 0, whose teeth engage withthose of the bevel- 4 5 gear wheel E at the proper time, as hereinaftershown, and the gear-wheel 1), whose teeth en- 'gage with the gear-wheelF, which latter is made enough thickerthan D to allow the two wheels toremain engaged when the wheel F 5c is slipp'ed'forward, as hereinaftershown.

R is a shaft or rod, one end of which is supported by a proper bearingupon A, the other end entering into and playing in the hollow spindle ortube T, with which it is connected by the screw W, moving in the slot N.Upon the shaft R, at a proper distance between its bearing on A and itsentrance into the tube T, is fixed a circular disk, G, with a recess 0rcam cut in it, so that when the stud Q on the standard A, falls into it,the shaft Rfmay be thrown forward the depth of such recess by the springS into the tube T, against the rear of the movable jaws J J, pivoted tothe tube T. These jaws are semi-cylindrical in shape, tapering somewhatfrom rear to front, and are laid longitudinally along the front of thetube T. On the inside of these jaws, at the rear, are beveledprojections or studs, against which the beveled end of the shaft Rpresses when it is thrust forward by the action of the spring S, thuspushing the rear of the jaws apart and closing them in front as they arepivoted to the tube T at points in advance of their center (in length.)

Upon the tube T, near the entrance of the 7 5 shaft R, is thegeared-wheel F, with a projection or cam, X, to act upon the elbow ofthe handle or arm of the holding and cutting apparatus Z. Near the otherend of the tube T there is fastened upon it the cam-disk P, the recessof which engages, at the proper time, with the corresponding projectionof the bearing-guard V, by the action of the spring S.

The tube T is recessed on top to receive the latch or spring L, whichhas at its forward ex- 8 tremity an arm bearing a cord-carrier, K. Thiscord-carrier is fastened to this arm by the spring-rivet a, or otherwiseso arranged as to have a forward motion on the pivot and a -quickreturn, as shown in Fig. 7. The carrier end of this latch is depressedby the bearingguard V, as shown in Fig. 4, and allowed to spring backwhen it reaches the point b by a recess in the bearing-guard. (Shown inFigs. 4 and 5.) A

M is an arm, with an oblong slot, f, borne upon the extended journal 9of the wheel E, and having a pin, cl, moving in the curved slot 6 in ashoulder on the standard A as shown in Figs. 1, 4, and 5. The revolutionof E draws 10o the arm M up and back, carrying the coldcarrier K on thefront of the arm over the jaws J J, as shown in Fig. 3, from whichposition it is retracted by the spring 5 or its equivalent. Thecord-carrier K is curved like the upper half of the letter S. ln each ofthe cord-carriers K and K there is a V-shaped slit with serrated edges,designed to facilitate catching and holding the cord.

Z is a holder, carrying on its upper surface cutting-blades, which areomitted from the drawings for distinctness, and is formed like a pair ofshears, moved backward and opened by the engagement of the cam or wedgeXon the wheel F, with the elbow of the handle 11 drawing the handlesback against the pin or stud y, and thrown forward and closed when X haspassed out of the elbow by the helical spring S or its equivalent.

Although I have described and shown an arrangement of the jaws J J bywhich they are shut in front by the pressure of the beveled end of theshaft R on projections in the rear of thejaws, I do not limit myself tothat method of operating them by the shaft It, for, as will bereadily-seen, that shaft may be prolonged into the jaws, and so beveledas, in connection with corresponding beveled projections on the insideof the jaws, to force them together or shut them in front, and to openthem in front when the shaft is pushed forward or retracted.

The operation of my machine is as follows: The grain is supposed to bedelivered at the right of the binder. The end of that portion of thecordwhich, in forming the loop, is passed under the gavel being held by theholder Z is, by the motion of the throwing-arm, drawn back over the jawsJ J. The arm is then thrown forward and over the grain, carrying thecord toward the holder Z. The shaft It is revolved from thedriving-shaft B by means of the geared wheels F and l) on the former andlatter, respectively, the spring or latch L being open and raised abovethejaws. As the revolution of R continues the recessed cam on the disk Pis brought opposite to the recess in the bearing-guard V, and forcedinto it by the spring S. This throws the tube T, carrying the jaws J J,forward, so that the cord which is held by Z, and that which is beingsupplied by the throwing-arm, both of which have been lying on the jaws,are brought under the upraised latch L under the notch in thecordcarrier K. As the revolution of It continues the latch or spring Lpasses out of the recess b of the bearing-guard V, and is forced downagainst the jaws, clamping firmly the cords between itself and thejaws.The wedge or cam X on the wheel F engages in the elbow of the handle Hof the holder Z, opening the leaves of the latter against the stud yandreleasing the cord held by it. The revolution of R continuiug,thecamXpasses ontof the elbow of H, and the holder Z is then pulled forwardsharply by the spring S closing the leaves of the holder upon the cordjust brought over by the throwing-arm. The cutters on the upper surfacesof the shears of the holderZ cut off the cord just above the surface ofZ, leaving an end of cord for the next loop nipped in the holder, asshown in Fig. 4.

The cord-carrier K catches the loose ends q q of the cord in itsserrated notch, while the continued revolution of R winds the cords ofthe loop between the latch L and the gavel around the jaws, as shown inFigs. 5 and 6, the effect of the pressure of the cord upon the jawsbeing to close them in the rear and open them in front at c. Meantimethe segmentgearing on the wheel 0 engages in the gearing of the wheel E,causing this wheel to revolve and raise the arm M, with the cord-carrierK upon it, upward and backward over the jaws J J toward thebearing-guard V. By the time this arm has reached a vertical positionthe cord-carrier has arrived in front of it, carrying in its notch theends q q of the cord, as shown in Fig. As the movement of thedriving-shaft B continuesthe teeth of the wheel (3 are disengaged fromthose of the wheel E, and the arm is forcibly retracted to its originalposition by the spring 8. As it moves down in an arc with a shorterradius, caused by the play of shaft 9 and pin (1 in the slotsf and c,the end of the arm M, bearing the cord carrier K approaches the jaws JJ, and the cord-carrier K seizes in its notch the ends q q of the cordheld MK, and forces them down on the end of the tube T between theopenedjaws J J into the opening cover the loop that has been laid around thejaws. In this movement the forward motion of the cord-carrier K (shownin Fig. 7 facilitates the delivery of these cord ends q q. The stud Qthen falls into the recess on the disk G, and the shaft R is forcedforward by the spring S, so as to open the rear of the jaws J J and shutthem in front, nipping the ends of the cords q q that have been forcedinto the opening a by the carrier K. The latch L passes into the recessb in the bearing-guard V, and, springing up, releases the loop beneathit, which slips forward off the jaws J J, from the natural strain of thebound grain over the ends of the cords held fast by the closed jaws. Theshaft It still revolving, the cam on the disk G is passed, the shaft isdrawn back, and the ends of the cords q and q are freed, but not untilthe loop has passed over them and a secure loopknot has been formed.

I claim- 1. In automatic grain-binders, the drivingshaft B, with thewheels (J and D, the shaft R, carrying the recessed disk G, bearing uponthe stud Q, and the wheel F, with the cam X engaging in the elbow of thehandle H of the cutting and holding apparatus Z, the tube T upon theshaft R, carrying the cam-disk P, eugaging in the bearing-guard V, thetapering semi-cylindrical jaws J J, operated by the shaft R and thepressure of the cord in forming the loop, and the latch L, with thecordcarrier K, the arm M, with the cord-carier K,

actuated by the wheel E, combined and operated as herein described.

2. The arm M, bearing the cord-carrier K in combination with the wheel Eand the jaws J J, so constructed that its arc of movement is shortenedas it forces the cord-ends q g y from the cord-carrier K into theopening 0.

jaws J J to form the loop, while the cord-carrier K retains the looseends q q for the action of the arm M and cord-carrier K sub- 1stantially as described.

In testimony whereof I have signed my name to this specification beforetwo subscribing' witnesses.
